Outer Limits 4x4 Board

Hi,

just wondering if anyone has any info on this.. ie, what supercharger, mounting, performance gains, costs, etc.

I'd like a turbo and have investigated that considerably but haven't really seen much in regards to supercharger instead.

any info is appreciated.

Thanks!

I am in the process of doing this at the moment, It isn't an easy task. If I had my time over again I would have gone the turbo option for sure but at the time I was sucked in by the lure of low revs boost and a flatter torque and power curve.

Luckily I have a very good mate who is a fitter & turner/Machinist/Diesel fitter of considerable skills and experience. Without his help I would not have attempted it.

I'm using and SC14 supercharger (used in the MR2 spiders) which are avaliable for about 400 bucks from importers, Firstly I remove the aircon compressor and fabricated a mount to fit the SC in it's place, Next we got a Multi-V belt pully off a V6 commodore, Machine it down so we are left with just the outer pulley ring, then we machined a hub to mount the pulley ring to the crank. We then machined a pulley for the blower that matches the crank pulley (the blower has to be ran at about 1:1.9 crank:blower speed). We still have to built a belt tensioner for the thing and pipe it in. I apologise if I have made it sound easy because it hasn't been, ther are always a thousand little jobs that also require doing in this sort of thing. Eg. removing the fan and shroud and fabricating a new flatter shroud for a thermo fan, Making a new R/H/S radiator support, and there are many more.

If you want my opinion on the matter just save your money and buy a low K's 13BT, It is just a better engine than a turbo or supercharged 3B. But failing that If you are pretty handy or have a mate who is built your own turbo sytem because once you have dropped 3K on a shop fitted turbo system (which I'm guessing would be going on an engine that has already put the best years of it's life behind it) you have half paid for a low K's 13BT.

phroaar.. definitely sounds like a lot of work, and fiddly work at that..

I might stick to the home grown turbo idea (just need to find a suitable exhaust manifold) and go down that road.. I figure about $1500 for a homegrown turbo installed.. which would be relatively straight forward to throw on my current 3b or a replacement if I happen to blow this one up.

thanks for the response bee-jay.. i saw you mention it in another thread and was keen to find out how far you had got with it and what you expected out of it..

cheers,

I looked at the turbo option and these are some of the avenues.

1.Find a 13BT turbo manifold from a wrecker. It will bolt straight on (bearing in mind there is a 2 and 3 stud pattern for exhaust manifolds). I couldn't find one or find a wrecker willing to seperate the manifold from the engine. The 13BT wasn't that widely used in oz but you could try overseas, In Canada there was a BJ60 sold which was a 60 series with a 13BT, you might have more luck there.

2.I have seen people make an adapter which will allow you to bolt a turbo onto the outlet of a standard manifold. It mounts it "upside down" to how you are used to seeing turbos mounted. But I imagine an adapter could cost big dollars if you had to pay to get it fabricated.

3.I have seen people cut the turbo mount from another engines manifold and weld it on top of the standard manifold, you have to cut a whole in your manifold and cover the standard outlet with a blanking plate of course. You will need a welder of quite some skill for this one but because weld two pieces of cast together isn't easy. The upside but is that the donor manifold and turbo can come from any engine so it will be easy to source.

Hope this helps.

buy a side mounted supercharger from a jap importer, they come off some imported toyota engines, s12 and s14 are the two common ones. they are cheap as. just make up some brackets and pipe work and it will be sweet, have seen these superchargers used on petrol and diesel hilux's.

What about driving the charger?

BEE-JAY whats your 3B in? where in Townsville are you? im on the island
